The word ‘myofascial’ has two parts. ‘Myo’ means muscle and ‘fascial’ means fascia. Fascia is a network of elastic tissues running through your body. Every muscle has an outer sheath of fascia. This stretchy coating cushions impact and allows muscles to glide over each other. Microscopically, fascia is composed of a three-dimensional network of stretchy fibers. When your fascia is healthy, it is soft and flexible. But when you have an injury, long periods with poor posture, repetitive motion, poor nutrition, or high stress, fascia can become tough and inflexible. Tight fascia can cause pain, reduced range of motion, and lead to damage of your muscles, joints, and tendons.
Similar to the Myofascial Release massage technique, cupping provides a sustained stretch of the fascia. The long gentle stretch provided by cupping gives time for nutritive fluids to flow into the opened spaces and elongates the fibers.
When working on tight muscles, it helps to think of muscles and fascia like rubber bands. When you stretch them occasionally, they’ll quickly return to their tight position. It’s only when you release tension frequently and improve circulation that you can make lasting changes.
